Energy efficiency and conservation measures help to reduce energy consumption, which in turn reduces greenhouse gas emissions and air pollution.

The industrial sector is responsible for the largest share of global energy consumption, accounting for about 30% of total energy use.

Energy efficiency refers to the use of less energy to perform the same task or produce the same amount of output.

Using renewable energy sources is an example of a renewable energy measure, not an energy efficiency measure.

Energy conservation refers to the reduction of energy consumption through changes in behavior and lifestyle, such as turning off lights when leaving a room or unplugging appliances when not in use.

Energy conservation measures help to reduce energy consumption, which in turn reduces greenhouse gas emissions and air pollution.

Renewable energy refers to the use of energy from renewable sources, such as solar and wind power.

Nuclear energy is not a type of renewable energy because it does not come from a renewable source.

Sustainable energy refers to the use of energy in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Sustainable energy principles include using renewable energy sources, reducing energy consumption, and protecting the environment. Increasing greenhouse gas emissions is not a principle of sustainable energy.

Climate change mitigation refers to the process of reducing greenhouse gas emissions from the energy sector.

Building more coal-fired power plants is not a strategy for climate change mitigation in the energy sector because coal is a fossil fuel that emits greenhouse gases when burned.

Climate change adaptation refers to the process of adapting to the impacts of climate change.

Increasing the use of fossil fuels is not an example of a climate change adaptation strategy because fossil fuels contribute to climate change.

Decarbonization refers to the process of reducing greenhouse gas emissions from all sectors of the economy.
